Case Study

25 Turbines. 400 Components. Due Diligence in 48 Hours.

How one acquisition team used Ridgeline to complete a full technical due diligence campaign for a 37.5 MW wind farm — without a single spreadsheet.

Spreadsheets don’t scale past your first wind farm.

Every acquisition starts the same way. Someone builds a spreadsheet. Then another one. Then a third with a slightly different column layout. By the time you’re reviewing your fifth project, you have:

  • Component serial numbers in three different formats
  • Condition scores that don’t match across campaigns
  • Gearbox replacement history buried in email threads
  • No way to compare risk profiles across your portfolio

The Sweetwater Wind Energy Center — a 25-turbine, 37.5 MW GE 1.5sle project in Texas — was the team’s third acquisition in six months. The previous two had taken 3+ weeks each for technical DD alone.

A structured database from the first turbine.

The team loaded Sweetwater into Ridgeline and ran due diligence using the platform’s campaign workflow.

What Ridgeline handled:

Turbine onboarding

25 turbines with specs, GPS coordinates, and commission dates — auto-populated from GE 1.5sle template

Component registry

400 components across 14 categories per turbine — gearboxes, generators, main bearings, blades, transformers, pitch systems

Condition assessments

536 individual assessments with 5-point condition scores, remaining useful life estimates, and failure mode flags

Data quality scoring

10 operational areas scored (SCADA availability, CMS coverage, maintenance records, cybersecurity posture)

Financial analysis

Capacity factor validation, AFCR calculations, and air density corrections — all automated

Risk register

7 risks identified and tracked with probability/impact scoring and mitigation plans

Before Ridgeline vs. After

DD campaign duration

3+ weeks → 48 hours

Component data entry

Manual, per turbine → Template-populated

Condition scoring

Variable → Standardized 5-point

Risk tracking

Email threads → Structured register

Data carried to ops

~30% → 100%

GO/NO-GO docs

PDF report → Live audit trail

The DD database becomes the operations database.

With spreadsheets, acquisition data dies at close. Serial numbers get re-keyed (if you’re lucky). Condition assessments sit in a PDF nobody opens again. Component replacement history starts from zero.

With Ridgeline, the data you collect during due diligence is the same data your operations team uses on day one. Nothing gets lost. Nothing gets re-keyed. The gearbox condition score from your site visit is still there when you’re planning the first major overhaul.

“We used to spend the first month after close just rebuilding the asset data we’d already collected during DD. With Ridgeline, our operations team had everything on day one — every serial number, every condition score, every risk flag.”
